目的观察颈动脉内膜切除术(CEA)后对侧颈内动脉变化情况。方法回顾性分析127例因一侧颈内动脉高度狭窄而实施CEA病人的临床资料,每隔1年行1次双侧颈动脉超声检查,定期检查双侧颈动脉狭窄情况。结果随访1~110个月,平均32.8个月,从实施CEA到对侧颈内动脉出现显著狭窄时间为50.7个月;出现对侧颈内动脉进行性狭窄达70%以上12例。这12例虽合并高血压、高脂血症或冠脉疾病,但与非进行性狭窄病人经统计学分析无显著差异(P>0.05)。结论 CEA术后对侧颈内动脉出现进行性狭窄的显著危险因子尚未发现,定期检查及密切观察预后非常重要。
Objective To observe the change of lateral internal carotid artery after carotid endarterectomy (CEA). Methods A retrospective analysis of 127 cases of CEA due to a high degree of stenosis of the internal carotid artery in patients with clinical data, every 1 year line of bilateral carotid artery ultrasound examination, regular bilateral carotid stenosis. Results The follow-up ranged from 1 to 110 months (mean, 32.8 months). The time from the CEA to the contralateral internal carotid artery was 50.7 months. There were 12 cases of more than 70% progressive contralateral carotid artery stenosis. Although these 12 patients had hypertension, hyperlipidemia or coronary artery disease, there was no significant difference (P> 0.05) between them and non-progressive stenosis patients. Conclusions The significant risk factors for progressive stenosis of the lateral internal carotid artery after CEA have not been found. It is very important to observe regularly and observe the prognosis closely.
